r3276: - allow for more than 256 open old style searches (limit currently set at an arbitrary 5000)
- auto-cleanup old searches that the client forgot to close (common with old searches) - expanded the RAW-SEARCH test to test more than 256 old searches, and old search rewind (w2k3 fails this - it appears to not support rewind on old style searches) (This used to be commit bc83d823b2140a10007490bf0101843a886f99a6)
